Frequently Asked Questions

What is an API hydrometer used for?

An API hydrometer measures the specific gravity of petroleum products and crude oil according to the American Petroleum Institute (API) scale. This ASTM Plain Form model with a 19/31 range is used in refineries, labs, and fuel testing to determine API gravity, which indicates fuel density and quality.

What are the specifications of the API ASTM Plain Form hydrometer GW003H?

The API ASTM Plain Form hydrometer (MPN GW003H) has a range of 19/31, scale divisions of 0.1, and an overall height of 13 inches. It is designed for precise gravity measurement of petroleum liquids and meets ASTM standards for accuracy.

Where to buy API hydrometer GW003H worldwide?

3G Electric supplies the API hydrometer GW003H worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us to order this ASTM Plain Form hydrometer with a 19/31 range and 0.1 scale divisions.

How to select the right API hydrometer for fuel testing?

Select an API hydrometer based on the expected API gravity range of your fuel. For crude oil and light products, a 19/31 range with 0.1 divisions offers sufficient precision. Ensure the hydrometer is ASTM-certified and has a plain form design for easy reading in a standard cylinder.
